APDUscanner

CAUTION: if you don't want to get your cards blocked, be careful to avoid brute forcing CHV/PIN APDUs.

APDUscanner is a small tool to explore ISO-7816 cards using a trial-and-error approach. You may use it to scan your smart card for undocumented commands, to discover the file system layout ("SELECT FILE" iteration), or just to have fun.

For Chipknip cards (Chipknip is a Dutch payment standard): read the public Chipknip information (account number, balance, last payments)

Warning: if you want to prevent your card from being blocked, make sure that you don't instruct APDUscanner to brute force known command APDUs for PIN-related commands (PIN verify, PIN change, et cetera). You're probably OK if you simply disable range-scanning on P2 and P3.
